Darkness on His Bones (A James Asher Vampire Novel)

War is descending on the world, and James Asher is called to Paris. Why, his wife Lydia has no idea. But when James is found unconscious in the cemetery of the Church of St. Clare with multiple puncture-wounds in his throat and arms, there is only one person Lydia can call on for help: their old friend and adversary, the vampire Don Simon Ysidro.
